Determinación de la concentración de residuos de clortetraciclina y su actividad antimicrobiana en deyecciones de pollos broiler
(Universidad de Chile, 2017)
La familia de las tetraciclinas, es la segunda familia de antibióticos de mayor producción y uso a nivel mundial. En la industria avícola, son utilizadas para tratar enfermedades infecciosas de origen bacteriano, sin ...
Performance, health and physiological responses of newly weaned feedlot cattle supplemented with feed-grade antibiotics or alternative feed ingredients
(2018-03-26)
With increased regulations regarding the use of feed-grade antimicrobials in livestock systems, alternative strategies to enhance growth and immunity of feedlot cattle are warranted. Hence, this experiment compared ...
Characterization of the europium tetracycline complex as a biomarker for atherosclerosis
(Bellingham, Washington USA: Society of Photo-optical Instrumentation Engineers, 2017)
Techniques for sperm evaluation using fluorescent probes
(2015-01-01)
A variety of laboratory tests were developed to obtain more reliable results of sperm evaluation and increase the accuracy of sperm fertility predictions. These tests detected damage of sperm specific compartments or ...
Effect of heparin on in vitro capacitation of boar sperm
(Sociedad de Biología de Chile, 2006)
Participation of membrane adenylyl cyclase in heparin-induced capacitation in cryopreserved bovine spermatozoa
(Wiley, 2014-01)
The aim of this work was to study the participation of membrane adenylyl cyclase in heparin-induced capacitation in cryopreserved bovine spermatozoa. Sperm suspensions were incubated in Tyrode´s albumin lactate pyruvate ...
Capacitation inducers act through diverse intracellular mechanisms in cryopreserved bovine sperm
(Elsevier Science Inc, 2010-10)
The effect of various capacitation inducers, i.e. heparin, superoxide anion, bicarbonate, adenosine, and caffeine, and their role in intracellular mechanisms involved in capacitation, were studied in cryopreserved bovine ...
In silico-guided drug repurposing: identification of non-competitive inhibitors of Trypanosoma cruzi and Plasmodium falciparum cysteine proteases
(Fundación Revista Medicina, 2020)
Abstract/Resumen: Trypanosoma cruzi and Plasmodium falciparum are the etiologic agents of Chagas disease and Malaria, respectively. Cysteine proteases play key roles in the pathogenesis and survival of these parasites, ...
Multidrug resistance pump AcrAB-TolC is required for high-level, Tet(A)-mediated tetracycline resistance in Escherichia coli
(Oxford University Press, 2006-07)
Objectives: Starting from the observation that Escherichia coli tolC mutations severely reduced the high-level resistance to tetracycline afforded by Tn10- and plasmid-encoded Tet(A) pumps, we studied the mechanism of this ...
